Recovering Snapshots After a Pool Capacity Failure

Recovering Snapshots After a Pool Capacity Failure
If pool capacity becomes exhausted, all snapshots within that pool (and all the
volumes on which the snapshots are based) go offline, and Adaptec Storage
Manager generates a failure message.
When a pool capacity failure happens, the write that exhausted the pool’s capacity
is failed back to the iSCSI initiator that wrote it.
Note
For more information, see “Ensuring Pool Capacity for Your Snapshots” on
page 67.
If you receive a failure message, follow these steps to recover your snapshots:
1
Recover or create available space in the pool:
• Delete unneeded volumes from the pool (see page 94).
• Add storage capacity to the pool (see page 90).
• Delete all the snapshot sets associated with the volume (see page 66).
2
In the Snapshots View, select an offline snapshot to highlight its snapshot parent,
then select the snapshot parent.
3
In the
Actions
menu, select
Set snapshot group online
.
Note
If the Set snapshot group online menu option is greyed-out, recover or
create more space in the pool, following the suggestions in Step 1.
4
Click
Yes
to confirm.
The snapshots are recovered.
Using the Reset Button to Perform a Limited Reset of the
Appliance
The Reset button is accessed via a small hole next to the Power button on the front
of the server. Verify that the server is fully booted (as indicated by the System LED
blinking once per second), and push the
Reset
button. The system will reboot after
about a minute. As a part of the reset and reboot process, the Snap Server 700i
Series:
• Clears user-defined settings such as DHCP configuration
• Resets the server name to its default setting (
SNAP<server number>
)
• Resets network speed and bonding settings to their defaults
• Resets the Administrator password to the default (
admin
)
• Resets the Operator password to the default (
admin
)
